I carry an embarassment of calls but do most of my hunting with a Primos Cuttin' hen in my mouth. Hooks makes a good call, Ray Eye's stuff is good. Basically everybody makes a good call, finding the one that suits you means trying a bunch. And the bad thing is no one is going to lend you one for a trial run
I truly think that most of the time any call will work and knowing when and how much or little to call is vastly more important. I've called a fair number of birds to the gun by mouth with no call (and at times, as in duck calling, I believe it's more effective).
I've been lucky enough to hunt with some super turkey hunters, spent a fair amount of time with Ben Lee in the '70's (my brother shot his first turkey while leaning against Ben's belly when he was 14) and what they were the very best at was being a good woodsman first (knowing terrain and what turkeys tend to do in certain places) and calling next.
I can't keep from carrying a bunch of calls though. Just in case.
